IMPROVEMENT IN TONG-UES FOR HARVESTERS.

To all whom it ma/y concern: Y

Be it known that I, J osEPuv VADLEIGH, of Ohebanse, in the county of Iroquois, and State of Illinois,

Tongues for Reapers and Mowers; -aud I do hereby declaro and make known that the following is a'full, clear, and exact description thereof, reference being had to the accompanying drawings, and the letters and tigures marked thereon, which form part of this speciication.

My said invention consists in constructing the tongues of reaping and mowing-machines, or other vehicles hav,- ing a side-draught, with a joint just in front of the point where the double-tree is attached,y of such construction that the tongue is rigid and stiif when the machine is being drawn forward, but that will allow the tongue to turn laterally at said joint when. the horses are guided to one sideto turn the machine in another direction, so as to relieve-the necks oi' the horses from the leverage of the tongue in turning, as is the case with tongues of the ordinary construction, said tongue resuming its original position automatically as soon the draught comes in a direct line with the stationary part of the tongue or draught-pole, as is hereinafter more iiilly and explicitly set forth.

To enable those skilled in the art to understand how to construct and use my said` improvement, I will proceed to describev the same with particularity, making reference, in so doing, to the aforesaid drawings,in which- Y Figure l represents a .plan or topI view of my invention Figure 2 represents a similar view when the machine is being turned from its former course;

Figure 3 is a side view of the same;

Figure 4 is a central plan section at the line w in fig. 3- and 7Figure 5 is a central vertical section at the line x in g. l.

Similar letters of reference in the several figures denote the same parts of my invention.

A represents the stationaryl heel ofthe tongue, which is rigidly attached'to the frame of the machine in any snitablemanner, and which is constructed with a hori- 'zontal recess extending back from its front end a sufiicient distance, and entirely across the piece A, as indicated clearly in fig. 4, where said recess or slot is marked a, its middle part extending farther back than its sides, forming a sloping-faced socket, as indicated in said fig. 4.

The movable part of the tongue, marked B, is provided, at its rear end, with a horizontal central tongue or tenon, b, which passes back into the aforesaid slot in A, its rear end conforming to and fitting into the rear end of the said slot, as indicated.

The object in having a socketat the rear endoi' the recess a, and a corresponding point on the rear end of The Schedule referred to in these Letters Patent and making part of the same.

the tongue b, is toprovideibr making the draught-pole rigid when backing; and the object of having a longitudinal movement in the pole B, is to enable the poley to be moved forward out of said socket, so as to be swung around.

The part marked A may be made of wood or iron, and, ifl desired, may be cast `upon and with the frame ofthe machine.

'Fliese two parts are then pivoted together by a pin, P, which pin also secures the double-tree C in place, and passes through a longitudinal slot, marked c, in the tongue b of the movable draught-pole, as seen in tigs. 4 and VF F lrepresent metallic straps, securedupon the top and bottom of the heel A, at the point where the pin I passes through, to form bearings for the shoulder ou the pin P and the nut m at its lower end, as shown in iigs. 3 and 5, the shoulder on the pin and the lower nut m serving to hold the jaws of A together, and strengthening them.

The double-tree is held upon the pinP and thetongue A by means oi' a nut, n, or said pin P mightvbe provided witl a head for that purpose, Aif desired. But, by having a nut upon the upper end of said pin, and a shoulder resting on the top 0f the piece A or strap Fthe double-tree can be removed Without withdraw; ing the pin P from the joint in the tongue or pole.

E represents a continuous band, passing around A, just at the rear end. of the aforesaid recess a, to strengthen the same.

D D represent metallic straps, secured upon each 'of the members of the part A, above and below the* recess (t, for the purpose of securing in proper position, upon one or both sides of the tongue, certain supports or lugs :l d', shown, through which a pin, 1), may pass, and in which it may be securely held in place, asdesi red. Said lugs el cl are required upon only one side of the tongue, and may be secured in any suitable manner,v the side upon which they are to be placed being determinedin each machine on the point as to which side of the tongue the side -draught comes, or, in other words, thc direction in which the machine is required to be turned when in use. However, lugs may be placed upon both Qsides, in order that when the machine is being moved from place to place, not being in use, pins may be put in on both sides, to render the pole B rigid, and enable the machine to bc turned in either direction.

G represents a chain, which is connected to the heel or rear part of the tongue l), as is clearly seen in iig.

2, and also to the stationary part A, to prevent thepole B from swinging around too far, .to get the horses into or too close to the sickle.

The end of the double-tree G is also connected to `said' chain =G by a chain, H,which serves to preventthe evener or.- double-tree from swinging around toofar and getting in the way ofthe reel, and also serves to hold up the chain G, to keep it around the heel ofthe tongue b, as indicated in iig. 2, and prevent its falling below said tongue b, which would allow the pole B to swing around too far.

Ifdesired, the chain H eouldbe connected to a suitable fastening upon the part A, insteadof being attached to the chain G.

From the foregoing description, it will readily be understood that when the machine is being fhawn forward by a draught upon the double-tree, the tongue Lb sets back its entire length into the recess a, as is indicated in iig. 1.

The side-draught being upon the side upon which the pin p is arranged, it is obvious that the pole B remains ligid when in this position, as the point of the tongue b sets back into the corresponding socket at the rear end ofthe recess c, and thus prevents the rear end of the pole .'B from slipping out of its recess or rest in A.

But when the said forward draught ceases, and the horses commence turning around towards the side on which the pin p is placedfthe Vforce upon the front end of B moves it ibrward, and withdraws4 the tongue b from its socket in c, as indicated in iigl 3, so'ythat the. pole B may swing out upon one side, as clearly shown in fig. 2, the chain (Jr preventing a movementtoo close. to the cutter, as aforesaid, and the chain H also operating as aforesaid.

As soon, however, as the pole B gets in line with the part A, and the direct draught is applied to move the machine forward, the pole B moves back, the point of the tongue b, entering` the socket in c, when the sidedraught gives rigidity to the pole B, as desired.

Instead of the chain G, any other suitable device may be employed as a stop for the swinging of the 'pole B.

It will be observed that 4the point and rear end of l1 is faced with metal, to prevent its wearing out, and also that metallic plates are applied upon each side of the tongue b where the slot'c is formed, to keep the said slot from being worn too wide.

Itmay further be observed, that any othersuitable arrangement, which will accomplish the same result. may he used in place ofthe pin p and its supports d d.

Having described the construction and operation of my invention, I will now specify what I clahn, and desire to secure by Letters Patent. I

1. I claim forming a lateral joint in the draughtpole or tongue A B, by means of a pivoted connection,

when a slight longitudinal movement is permitted in B, substantially in the manner and for the'purposes shown and set forth.

2. I claim, in combination with a draught-pole, A B, jointed as described, provided with a suitable stop, 1), the chain Gr, arranged and operating in the manner ushown and described.

3. I claim the combination of the double-tree C and chain H with the jointed draught-pole A B, arranged and operating in the manner set forth.

JOSEPH VVADLEIGH.
